An assessment of the performance of the four adsorbents obtained by upcycling of the AWs in terms of %R and qe. The experimental conditions are pH = 7.00 ± 0.20, initial drug concentration [SARA] = 40 ppm, adsorbent dose (AD) = 50 mg/15 mL, and contact time (CT) = 30 min. The obtained values of %R and qe shown were determined utilizing Equations (1) and (2).
| Candidate Adsorbent | %R | qe (mg/g) |
|---|---|---|
| Upcycled AWs | ||
| RPNS | 63.45 | 7.614 |
| TTPNS500 | 7.871 | 0.944 |
| ADAV | 29.15 | 3.498 |
| TTAV500 | 2.101 | 0.252 |
